What sets apart NativeScript minify for iOS and Android?

When building release apps in NativeScript, are there notable variations in the minification processes for iOS and Android? I am experiencing differences between the minified versions of the same JS file in Android and iOS release builds, leading to unexpected behavior in the Android JS file.

Upon running the minified JS through js-beautify, I observed significant syntax distinctions between the two platforms. For instance, the iOS JS file consolidates multiple lines of code into a single statement.

Answer №1

After delving deeper into the NativeScript source code, it became apparent that both iOS and Android platforms utilize terser for code minification. However, there are distinct platform-specific variations in the configuration settings used. In the webpack5 configuration:

       terserOptions: {
            // @ts-ignore - https://github.com/webpack-contrib/terser-webpack-plugin/pull/463 broke the types?
            compress: {
                collapse_vars: platform !== 'android',
                sequences: platform !== 'android',
                keep_infinity: true,
                drop_console: mode === 'production',
                global_defs: {
                    __UGLIFIED__: true,
                },
            },

While I still have lingering inquiries regarding the differences in the minified code produced by each platform, this information satisfactorily addresses my initial query.
